When I say unto the wicked, Thou shalt surely die; and thou givest him not warning, nor speakest to warn the wicked from his wicked way, to save his life; the same wicked man shall die in his iniquity; but his blood will I require at thine hand.
Thou givest him not warning, nor speakest to warn the wicked ... man. The repetition implies that it is not enough to warn once in passing, but that the warning is to be inculcated continually (2 Timothy 4:2. "Be instant in season, out of season;" Acts 20:31, "By the space of three years I ceased not to warn every one night and day with tears").
To save his life - Ezekiel 2:5 had seemingly taken away all hope of salvation; but the reference there was to the mass of the people whose case was hopeless-a few individuals, however, were reclaimable.
The same wicked man shall die in his iniquity - (John 8:21; John 8:24). Men are not to flatter themselves that their ignorance, owing to the negligence of their teachers, will save them (Romans 2:12, "As many as have sinned without law shall also perish without law").
